Someone has even used the picture to create "meme," seen here. The photo was edited with the addition of text. At the top of the image it says, "I usually don't go out to eat," and at the bottom, "But when I do, I don't pay."

Juan said the woman in the photo contested the automatic 15 percent gratuity and when she couldn't resolve the matter with staff, asked to speak to the manager.

When the manager and employee returned, the entire group had left, said Juan.

This is the explanation on the Mi Pueblo Facebook page, which Juan said is managed by a third party:

They had this planned, they were a group of 11. Whenever the group is 8 or more a tip is added, she went to talk to the cashier about it as the rest of the people with her walked out. She asked for the manager and when the cashier left to get him, she walked out also.

Juan said he wasn't sure, but believes the gratuity policy is printed on the menu.

Wait staff "are paid by hour but let's say the largest percentage of their salary is mostly tips," said Juan.

He said policy at the restaurant requires the wait staff pay 50 percent of any bill patrons skip out on, because "it's part of your job to collect the money from the customers."
